To all whom it may concern:

Be it known that I, Jenn flnxnr ITIALL, a subject of the King of Great Britain and Ireland, and residing at 51 Crescent road, city of Shetiield, England have invented certain new and useful Spare-ll heel-ll olding Devices of which the following is a specification.

This invention relates to means for remo ahly securing or 'athiching to the ordinary road wheel of a motor or other road vehicle a spare rim .-.arrying a. tire for the purpose of taking the load when the tire upon the ordinary wheel has become punctured or damaged in any way.

An object of the invention is to provide means for quickly and firmly securing a spare rim in position for the purpose above mentioned and also to prevent skidding.

Another object of the invention to so position the spare rim in relation to the wheel rim that an ample space is prmrided between the two tires so that no friction. or chafing can occur between them.

A further object to form such means as above referred to so that the spare rim secured to the metallic rim of the wheel and further, secured in such a manner as to prevent any creeping action taking place l;c tween the two rims.

in the accompanying drawingsz--l igure l is a part sectional elevation showing the invention as applied to an ordinary road wheel. Fig. i is an elevation showing a clamp and bracket attached, the spare 1 and tire are not shown. if perspective views of the clan bracket respectively.

In carrying out. the invention a sparra carrying a tire 7,- is titted with bracket preferably four in number; which ma? riveted or otherwise secured periphery of the rim in such a when the spare rim is secured there is ample space left hetweereither when the spare rim, i:-

latter be ng 1' l l I l of the wheel, .a small clearance being provided between the two, and is provided with a gripping portion 7c. similar to that upon the bracket 0 to engage the-beading f of the wheel rim. A nut. or the like Z is provided upon the screwed pin h so that the spare rim may be rigidly clamped to the ordinary road wheel. The gripping portions A and (Z are formed so that when fitted to the headings they do not in any respect interfere with the tire upon the wheel when telly inflated or otherwise, and as clearance is left between the telly j and the clai'nping derive 2', and the depending portion 0 of the bracket the gripping action takes place wholly upon the metallic rim.

It will be seen from the foregoing description and the drawings that the gripping action upon the rim of the wheel will he in 1 horizontal direction, or across the rim. in the event of any relative circumferential movement occurring between the two rims the el tips will tend to take up an Ubllk'lllfi posi ion so that the edges of the same will bind to the rim very tightly and. thus any tendency the spare rim may develop to creep with relation to the wheel rim will is prevented.

in order to attach the spare rim carrying the intlated tire tolhe ordinary road wheel, either in the case oi the usual tire becoming punctured or otherwise damaged or to pre vent skidding when it is preferable that the spare tire should studded or otherwise provided with a non-skid tread, the dependn portions e of the brackets are placed to telly j and 1 the same time the ppng pieces Z are fitted to the heading 7.
